An orphan at an early age, Loh was brought up by her maternal grandmother in Shanghai before the family moved to Hong Kong in 1949. From her youth, Loh had developed a passion for the performing arts and, in Hong Kong, lost no time in winning a contract at the Great Wall Film Studios in 1953. Despite major roles in films such as "The Peerless Beauty", Loh's five years at Great Wall passed uneventuflly. It wasn't until she signed with Shaw Brothers in 1958 that her star took on its eventual sparkle. Hits such as "The Enchanting Shadow" and "The Dream of the Red Chamber" firmly established Loh's reputation as the next big star and won her the nickname of "classic beauty". It was Li Han-Hsiang's "The Love Eterne" in 1962 that brought her to international recognition. Besides being screened at the 10th Asian Film Festival, the film went on to six awards at the 2nd Golden Horse Awards, among which was the Best Actress Award fro Loh. Loh was married to popular actor Peter Chen Ho in 1962 but, sadly, took her own life in 1968.
